Move top level lsp config to editor.lsp (#1868)

* Move top level lsp config to editor.lsp

This is mainly done to accomodate the new lsp.signature-help config
option that will be introduced in https://github.com/helix-editor/helix/pull/1755
which will have to be accessed by commands. The top level config
struct is split and moved to different places, making the relocation
necessary

* Revert rebase slipup
